On 10 May 2022, the European Centre for Disease Prevention and Control (ECDC) published its annual epidemiological report on Legionnaires' disease for 2020 in Europe.
In a summary of the report's major points:
- The overall notification report decreased from 2.2 to 1.9 cases per 100,000 of the population from 2019.
- Notification rates remained heterogenous across the EU and EEA, varying from fewer than 0.5 up to 5.7 cases per 100,000 of the population, with the highest rate reported by Slovenia.
- France, Germany, Italy and Spain accounted for 72% of all notified cases.
- Males aged 65 years and older were most affected, with 7.1 cases per 100,000 of the population.
- The number of reported cases to the travel-associated surveillance scheme decreased by 67% compared with 2019.
- Only 10% of cases were culture confirmed, possibly leading to underestimation of disease caused by Legionella species other than Legionella pneumophila.
